Hi everyone, just seeing if anyone is using a hondata s300 and could give me an insight on why my tables arent interpolating. Issue im having is in my flex fuel table, i have set the boost compensation to 100% meaning high boost map, however it is currently stuck in low boost table and would keep hitting my low boost cut.

Thanks for the help!

You will need to post the calibration as well as a datalog showing what you are describing.

Hi,
I have attached my datalog of the problem and my calibration. So my issue is the boost compensation in flex fuel seems to be glitching out as when I set the boost compensation to 100% in the flex fuel table, it still runs off the default/low boost table. Thanks for your help!

From your datalog and calibration it looks like you are running 99% duty cycle on the boost control solenoid.

Hi, the issue im having is there is a glitch in the flex fuel boost compensation where it would not interpolate over to high boost and will keep bumping into low boost cut and uses low boost table, this was only evident after the update so im unsure if its a software issue
